I modified the firewall ( cut it out for the muffler) to mount a Fuji 32 as close in as possible, Came out 14.5 pounds with the elevator and rudder servos in the tail. The previous weekend I saw one with a G-23 fly and mine didn't do that much better. I tried an APC 17x8 and a APC 18x6 wide 3D. Both turned at between 7400 and 7600 rpm. Who wants a stick that flies "scale like". Horizon list's the g-38 with a 18x10 at 7100 to 7400 rpm and it is heavier than the Fuji 32. If the numbers are accurate I wouldn't think it would be that impressive. Too much - no. Too heavy for the power out - probably. If I had it to do again I would go a little extra and go Fox or zdz. Hope this helps.
